Condition: used, Year of construction: 2017, pipe diameter (max.): 80 mm, mandrel length: 4,500 mm, Mandrel bending machine S8004 ----- For the production of dimensionally accurate pipe geometries with bending radii of up to 1.5XD → maximum bending performance pipe 76 x 4 mm (400 N/mm²) → maximum bending performance pipe 60 x 60 x 3 mm (400 N/mm²) → maximum bending performance pipe 76 x 2.9 mm (stainless steel) → total connected load 7 kW → pipe length 4.5 mtr Robust and durable steel construction in a force-locking connection - no construction susceptible to torsion due to, for example, the split construction of the bending head and mandrel carrier. Maintenance-free electromechanical drive of the bending axis. The touch display of the control enables simple and intuitive programming and use of the system. After the pipe has been pushed on, it is fixed in the carriage by the chuck. This enables the pipe to be positioned precisely and thus the creation of dimensionally accurate geometries. The standard also includes checking the pipe geometry before the bending process: If the bending process is started in the wrong position, the machine does not give permission for this. This prevents incorrect operation. Optional additional features provide more convenience and increase the output and thus the efficiency of the system. Data is exchanged from the optional pipe calculation program TBS-3D (PC version) via USB stick or via FTP access from the computer to the machine control system. USB or LAN connectors (RJ45) are available as standard. Existing pipe geometries can be converted quickly and easily, for example, using the STEP format. Standard equipment: → Electromechanical drive of the bending axis 4 kW → Speed 2.9 rpm (=17°/sec.) → Bending direction left → Bending angle resolution 0.1° → Max. bending radius 200 mm → Bending shaft diameter 50 mm → Electronic length measurement ±0.1mm → Electronic twist measurement ±0.1° → Manual stop system (overtravel stops in length) → Manual locking system (15° in twist) → Three-jaw chuck for locking the pipe in the carriage → External control panel PLC control: → Touchscreen 10.1" → ETH 10/100, X2X Link, USB → Foot switch operation → Data transfer via network (W)LAN or USB → Material database Unique graphic programming: Simple geometries can be calculated directly on the machine. The control calculates the feed values directly after entering the length and angle and the bending angles. Hydraulics: → Hydraulic power 3 kW → Hydraulic pipe clamping with adjustable clamping pressure → Programmable early mandrel retraction Options (can be ordered as additional equipment): → Variable bending speed using frequency converters or servo motors → Automatic tool retraction (manual or controlled) → Pneumatic chuck Iodpfx Aettah Rebvoic → Automatic mandrel lubrication → Pneumatic stop system (length + twist) → Mobile version (rollers) → Radius extension Pictures show new machine
